My DD2 will be 5 months on 23rd Oct. She's so grumpy and hungry! She's on Hipp Organic formula (milk gone at 7 weeks :( ), she's quite porky and she cant go more than 3 hours, 150mls/5oz bottles, in the day and one at night so total of 6 bottles/30 oz in 24 hours. But now she's not even going 3 hours, she seems so very hungry. I want to demand feed of course, but the windows are getting smaller and smaller...she used to go longer than 3 hours. I can try and up the amount in her bottles I suppose. So....anyone heard of a growth spurt at this time (she was two weeks early, so by some people's estimates she is 4 months), surely its too early for solids? She doesn't have any teeth and has a very strong head but cant sit up on her own. I cant change milk brands as I live overseas and I've had to import all the Hipp Organis milk, and I don't trust the brands here. Its very hot here, maybe we should be offering cooled boiled water too?
